The title says it all - this book really is complete. The author gives you almost more information than you want to know, but presents it in an interesting and efficient way. One of the strengths of this book is that the author has gained a lot of his knowledge by real experience. He has spent thousands of hours outdoors, studying animal behavior. He's also done lots of research. . He helps you make connections, such as learning what animals eat so that you can look for them or their tracks near their food sources. Just when you are reviewing his data and thinking, “Yeah, but what about this?” he goes there and answers all your questions. He also uses excellent examples to clarify points. I came away from this book with more knowledge than I expected. Well worth the read, even for an experienced outdoorsman.
